The Twin Cap with bayonet fitting, designed specifically for the Air Bubble Jets, gives forward and backward-facing angles to improve spray penetration. Enabling faster speeds, higher volumes and increased crop penetration. Also suitable for use with standard flat fan nozzles. The 30 degree forward and 30 degree backward facing nozzles in the Twin Cap, ensure optimal crop coverage and penetration under the crop canopy. This would be ideal on leafy crops such as potatoes for blight control.
